All fine until last restart

Concerning iMac G3 266, Friend of mine brought his old iMac 266 to hopefully update the system, after I checked and did firmware update first, I proceeded to update his iMac 266 to OS 9.2.2. Everything working fine then he inquired if it would run OS X, so went to install 10.2 but found we had not installed firmware update 4.1.7 so we quit OS 10.2 installer and restarted but upon restart computer froze, no response in anyway so had manually to power down unit, waited a while and went to power up computer and now show no power to anything, no orange light, nothing, reset PRAM, plugged unit back to power still nothing, what happened here?

Hey well the firmware version for the trays is 1.2 as far as I can tell. There was also an update to go to 9.2.2:

The trays aren't supposed to have the OS 10.2 firmware problem:

I'd try a PMU reset. It could be a flyback problem. Sometimes when this happens I'll pull the battery and power cord, push the power button and let the iMac just sit there. Sometimes for a week. When I come back often the problem is gone.
